Sommerfeldt is the largest and most prestigious manufacturer of catenary systems in all scales. For 50 years Sommerfeldt has been involved with model overhead systems and model pantographs. During this time the company gained supreme experiences, being able to develop the most prototypical overhead system yet. It is production-line system, that runs from mast to mast in straight sections under proper mechanical tension like the prototypes, and is recommended only for permanent and stable layouts. Masts are manufactured from steel profiles and are mounted with pedestal screws. All components are delicately manufactured without sacrificing stability and quality. The overhead system is easy to install and ensures reliable operation if properly tensioned. The overhead wires are made of copper plated steel and welded at the factory with open or closed sides. Easily installed on the masts by bending the ends into hooks or soldered in place for extra stability. This is the most prototypical wire system made anywhere ! All components are made and assembled in Germany.
